Wireless power transmission is fantastic in theory — but in practice, due to some pesky laws of physics, the range of transmission is extremely limited. Yes, you can now charge your phone by putting it on a wireless power transfer plate, but that plate still needs to be plugged into the wall, and — more importantly — you still have to remember to put your phone on the plate.
